This is a broad subject. Technology has never really been the issue of effectively monitoring an IT infrastructure. We've had the tools for over 20 years now and the problem has always been effective use of and implemenation of tools, It should start from the top with 4 things: a plan, a team/roles, the toolset, and processes to manage the infrastructure.

You raise the issue of non trivial methods so that suggests you're more interested in technical mechanisms. In this case it's best to ask something more specific. The best area I can point you to is this concept that is emerging and it's arguably steeped in virtualization. The concept is Reliability and Serviceabilty (RAS). Computation is becoming non-stop and this means that you can still compute and service the machine at the same time. Hardware reliability is well defined and there are predictive methods for handling this. In fact,every component, network, o/s... is well defined...so I don't really understand the "non-trivial" methods part. Whatever the specific, monitoring in general should support the emerging concept of RAS. Now that term has been mainly associated with hardware, but I think the concept extends to the entire infrastructure. I would be interested to hear more of what you have been working on and what you're targeting.

learning UNIX on a Windows 2000 machine?

What is the best way to learn UNIX, shell, and Perl on a Windows 2000 machine? My place of employment uses Solaris and Perl and I would like to learn some UNIX skills on my home PC. I read about "dual boots", "Microsoft Windows Services for UNIX", and "cygwin". What other free options are... (9 Replies)

clusvcmgrd(8)                                                  Red Hat Cluster Suite                                                 clusvcmgrd(8)

NAME

       rgmanager - Resource Group (Cluster Service) Manager Daemon

DESCRIPTION

       rgmanager  handles  management  of  user-defined cluster services (also known as resource groups).  This includes handling of user requests
       including service start, service disable, service relocate, and service restart.  The service manager daemon also  handles  restarting  and
       relocating services in the event of failures.

HOW IT WORKS

       The  service  manager is spawned by an init script after the cluster infrastructure has been started and only functions when the cluster is
       quorate and locks are working.

       During initialization, the service manager runs scripts which ensure that all services are clear to be started.  After that, it  determines
       which services need to be started and starts them.

       When an event is received, members which are no longer online have their services taken away from them.  The event should only occur in the
       case that the member has been fenced whenever fencing is available.

       When a cluster member determines that it is no longer in the cluster quorum, the service manager stops all services and  waits  for  a  new
       quorum to form.

COMMAND LINE OPTIONS

       -f     Run in the foreground (do not fork).

       -d     Enable debug-level logging.

       -w     Disable internal process monitoring (for debugging).

       -N     Do  not perform stop-before-start.  Combined with the -Z flag to clusvcadm, this can be used to allow rgmanager to be upgraded with-
              out stopping a given user service or set of services.
